While working on re-creating sveral things from SWtor ( starting with one of my characters sabers) I noticed a problem when I try and render right now- even in it's WIP state

It's a pretty obvious issue, it's those blades that appear out of nowhere and I'me pretty sure may be tied to the reflection perhaps? if not any insight woule be wonderful, can't say I've ever run into this one before.

it also seems to do it regardless of the render settings as well

also just for a clueless attempt, removed the shaders and re applied them changed lights etc, and no joy

Those black things are most likely due to one of two things:

Either you have some unconnected vertices in the model (I've had a similar thing happen with one of my models because of this) or,

There are lots of long thin polys in the model.  Poser tends to go crazy when it encounters those.  You can try making the polys not so long by halving or even quartering their length.  Yes, your poly count will go up but it should render correctly.  Another solution is to turn of Smooth Polys for this model.  That should also make it go away. 

THat may have been it, the elongated poly... I noticed in Maya that the little emitter tips were one long poly cylender going from one end to the other, so I just made it short, put it in place and duplicated it fot the other end, and it seemed to be fine.... I ALSO unchecked " keep normals" when importing too, not sure if that helpped at all

Smoothing. You had smoothing on.

Poser smoothing is not subdivision. It's very useful, but you must learn how it works. Or turn it off.

Yeah, for hard surfaces I turn off smoothing.

wonderful, it's rendering fine, I just need to figure out why It's notsaving as a smart prop...not that Im really bothered by that

thanks a billion everyone
